Axion interaction Lagrangian includes WZW terms and meson decays
—
Complete Lagrangian for axion interactions with mesons incorporating Wess-Zumino-Witten terms and instanton effects, enabling consistent predictions for axion decay widths.
True muonium production in J/ψ radiative decay may be detectable
True muonium production via J/psi radiative decay at electron-positron colliders offers experimental pathway to confirm QED prediction of muon-antimuon bound states.
